if l NM1, q n A11. a El ISU Enz/.l 6. u NQ ing upon thesey terminal portions is a rectan l gular wire stay member 26, the stay member being coupled to the respective .portions 25 by clipsi 2T, one of which is shown enlarged in Fig. il. The stay member 26 is thus an important feature of the construction, and materially strengthens the device against lateral movement, while at the same time i not materially increasing the weight or the expense of manufacture.

As damn in Fig. 2, all ci' the springs arel dispo-cd near thc upper portion of thcl back 14, so thai the upper portion of the upholstering. indicated by thc dotted line 24, is lirinly supported at` the point Where the greatest pressure occurs. so that the greatest resistance is pro\idcd whore most required.

By rcl'crcnce to Fig. 2 it will be noted that` the upper rou' oi springs 2O are arranged near thc upper end of the upholstei'fing, while the sccond row of springs 18 are spaced a short distance from the upper row, and the remaining rows of springs disposed a short distance below these, the shorter and smaller springs alternating with the longerand larger springs, as shown, so that when pressure is applied, the larger and longer springs receive the first impact and the siortcr and smaller sprinfs ecoine act-ive only when the larger and lon ercsprings have been deflected for a consi rable portion of their lengths. The larger sprlngs 'thus serve to hold the upholstermg portion of the cushion in position under ordinary conditions of ordinary pressure, but in the event of abnormal pressure being ap lied to the upholstering, as when the vehic e meets obstructions in the roads, the shorter springs then become active and materially increase the resistance and etl'ectually prevent undue collapsing. The contour of the cushion i thus maintained, and restored when the pres sure is Withdrawn, be of any required size or stren h and arranged at any distance apart, an the sprin s may be correspondingly sized to ada t te device to any of the various makes o 'automobiles and similar vehicles,

By the employment of this simple device, great saving of time and labor occurs, as no necessity exists for tying the individual springs in position, as in t ie construction of ordinary forms of spring cushions.

The invention is simple in construction and can be chea ly manufactured. In constructing a cu ion according to the improved means the frame, with the sprin s in position thereon, is placed against the ack 14 ofthe automobile and riveted fast thereto, and the upholstering material applied over the springs in the usual manner. All the springs of the cushion structure are thus ap hed simultaneously, which very materia y reduces the time and labor required The bands or bars may n to'.oohst1"uct a cushion, and dispenses with the necessity for tying each individual spring in position, as in cushions' heretofore constructed.

Having thus described the nature of the invention, what is claimed as new is:-4

l. A spring construction comprising a frame including horizontal bars and a series of spaced bars crossing the horizontal bars and at uniformly increasing angles from the center toward the ends thereof, a set ofV springs connected to th'e bars at their points ci intersection, an'other set of springs connected to thc bars oil' from their points of intersection and a substantially rectangular stay connected to the last mentioned springs to couple the latter together.

2. A spring construction comprising a frame including horizontal bars and a series of spaced bars crossing the horizontal bars and at uniformly increasin angles from the center toward the ends tiereof, a set of springs connected to the bars at their points of intersection, another set of springs connected to alternate angularly arranged bars and out of alinement with the aforesaid set of springs, one set of springs being longer than the other set of springs.

3. A spring construction for the backs of automobiles comprising a series of s aced horizontal bars and a series of spac bars crossing the horizontal bars at uniformly increasing angles from the center toward the ends thereof, with each alternately :ingularly arranged bar extendin at the ends beyond the remaining angu ar bars, and adapted to be connected to the seat back at the extended ends,l relatively lar esprings connected t-o thelongerA bars at t cir ]uiic ture with the horizontal bars and 'relatively small springs'connected to the shorter angular bars.

4. A springconstructioncomprisingafraine formed of horizontal and-a series of spaced bars crossin the horizontal bars, the two sets of bars eing connected together at their points of intersection, alternately arranged iorizontal rows of relativel large and-long and relatively small and s ort single cone' springs secured to the frame, the apexes of t le larger s` rings being directed toward the frame and t e apexes of the shorter s rings being directed toward the base of the arger springs, and a stay connected tothe a exes ofthe shorter springs to couple the atter together. f

5. A sprin construction comprising a frame forme of horizontal and spaced bars connected at their points or intersection, the alternately. arranged spaced bars being lon er than the remainingl spaced bars, the s orter spaced bars cach avin pair of tongues arranged upon opposite onts of intersection, and 'another set o llt sides of the horizontal bars, a set of springs nected to the shorter spaced bars by the tongues of the latter, one set of springs being shorter than the other set of springs.

6. A spring comprising a frame formed 4 of horizontal bars and a series of spaced bars crossing. the horizontal bars at uniformly increasing angles, the two sets of bars being connected at their points of intersection, the alternately singularly arranged bars being lon er than the remaining angularly arrange( bars, the shorter angulurly arranged bers, each having a pair of tongues arranged upon opposite sides of the horizontal bars, one set of springs connected to the bars at their points of intersection by the same means which connects the intersecting bars together, another set of other set of springs, and a substantially rectangular shaped stay member connecting the shorter set of springs:

7 A spring constructlon comprising horizontal bars and bau; crossin the horizontal bars and connected thereto, the alternately arranged second mentioned bars having tongues, one set of springs connected to the bars at their oints of lntersection by the same means which connects the intersecting bars together, and another set` of Springs connected to said alternate bars by means of said tongues.
